ILLUMINATING APPARATUS.

SPECIFICATION forming part of Letters Patent No. 425,154, dated April 8, 1890. Application filed June 27, 1889. Serial No. 315,764. (No model.) Patented in England September 29, 1888, No. 14,049.

To all whom it may concern:

Lancaster, Great Britain, (temporarily residing in the city, county, and State of New York,) have invented certain new and useful Improvements in Illuminating Apparatus, and more especially in means for pivotally connecting a burner with a supply-pipe, (for which we have obtained Letters Patent in Great Britain, dated September 29, 1888, No. 14:,0499 and we do hereby declare the following to be a full, clear, and exact description skilled in the artto which it appertains to make and use the same, reference being had to the accompanying drawings, and to letters ing-pipe O, the swivel-connection being, preferably, of the nature of that shown and deof reference marked thereon, which form a ,part of this specification.

Figure l is an elevation of our improved illuminating apparatus. Fig. 2 is a similar view showing the reservoir mounted on wheels. Fig. 3 is asection on line :0 0c of Fig. 1. Figs. 4 and 5 are sectional views of modified constructions of the pivotal connection,

and Fig. 6 is an elevation showing the burnerpipe as being portable relatively to a stationary source of illuminantsupply.

s This invention has relation to illuminating apparatus, and more particularly to that class which we term elevated lights, or in which the burner is at such elevation from its supply-reservoir as to be beyond reach.

The object of this invention is to provide means whereby ready access may be had to the burner when this becomes necessary from any cause or for lighting the lamp.

' The lamp or illuminating apparatus is more especially designed for out-door illumination or for use on board ships or for any other purpose where an elevated light maybe desirable; and the invention consists in the swiveling of the supply-pipe to the distributing-main or to said main and to a support for said burnerpipe, so that it may be swung around to bring the burner down within reach.

' In the drawings we have shown a construction of illuminating apparatus or lamp of our own invention; but it will be understood that we do not desire to limit ourselves to the suppipe from the reservoir shown,as the supplypipe may be connected to any other desired source of illuminant-supply.

A indicates the reservoir for the illuminat-v ing agent, which may be liquid or gaseous, though the apparatus is more especially designed for use with a liquid illuminating agent, such as hydrocarbon oil.

B is the supply-pipe, through which the oil is forced by compressing the air in the reservoir, in that the oil is forced into the reservoir and the air therein compressed. Any other desired means may, however, be employed for forcing the oil through the servicepipes.

To the supply-pipe B is swiveled a connectscribed in our application for patent, Serial No. 315,400, filed June 2-1, 1889, though any other fluid-tight pivotal connection may be adopted. The connecting-pipe O is similarly swiveled to a three-branch union D, intoone branch d 01": which is screwed a stuffing-box gland G, through the axial bore of which extends the end of the connecting-pipe. The branch (1 is screwed to a rod R, the foot of which is held in the eye of a bracket or sleeve s, mounted and sliding freely on a standard .S, the foot of which rests in a socket a, se-

Icured t0 the reservoir A near its bottom, and said standard. passes through a sleeve A at ior near the upper end of said reservoir. In stead of a solid rod R a tube suitably closed at'its upper end may be used. The standard S has a bearing 8' at its upper end for the key end 1) of a plug-valve P, screwed into the :union D through branch (1*. The end p of the valve is angular in cross-section, and the bearing 5 on standard S has a like opening to prevent the rotation of the valve in its bearings. The inner end of the valve P is bored or hollowed out, and it has a single port 19' communicating with its bore, into which projects the end of the connectingpipe 0. It is obvious that if the set-screw b is loosened and the bracket Z) allowed to slide plying of the illuminating agent to the burner burner-pipe being oii? the end of the rod R the said rod and the burner-pipe F, that is connected with the branch (1 of the union D and that carries the burner Il, may be rotated on the plugvalve P to bring the rod and pipe into a horizontal position and simultaneously therewith cut off the supply of oil to the pipe 11. In this manner ready access may be had to the burner for lighting it or for any other purpose.

In Fig. l we have shown a slight modifieation, in which the union D and its pivot are formed of one piece, the pivot or journal (1" revolving in the bearing .5" on the standard. Of course the flow of oil to the pipes will have to be cut off by means of the regulating-valve V or a stop-cock in the supply-pipe if the burner needs attention. By means of these pivotal connections the elevation of theburner may also be regulated.

In Fig. 5 we have shown the burner-pipe pivoted directly to the supply pipe, the said provided with a bearing for the valve-plug, which is screwed into an elbow of the supply-pipe. Although we have shown the supply and burner pipes supported directly from the oil-reservoir, it will be n11- derstood that this is not absolutely necessary, as the supply-pipe may be connected with any other desired source of illumiuantsupply, and its end and the burner-pipe and its pivot may be supported from any suitable stand or other support.

If desired, the burner-pipe and a portion of the supply-pipe may be made portable irrespective of the reservoir and connected therewith or with any other suitable source of illnminant-supply by a flexible pipe, as shown in Fig. 5. This arrangement may, for instance, be of advantage on board ship, as the reservoir may be below decks at any desired pointand connected with the burner by means of a flexible pipe B, connected with the pipe 0, as described, or otherwise.

When the swivel or pivotal connections between the burner- 'iipe F and the supply-pipe C and between the latter and the feed-pipe B are such as described in our application for patent hereinabove referred to, the burner and connecting pipes may be readily disconnected from each other and from the supplypipe by simply unscrewing the gland G. ()n the other hand, by removing the screw or pin 17 from the key end 1) of the valve the bu rnerpipe may be disconnected from its standard S, and the latter, simply resting in the socket l) and passing through the sleeve Z), may be readily removed from the apparatus. Finally, the burner-pipe and the retaining-rod maybe disconnected from the union-piece, and when the burner-pipe is a long one it may be made in sections, so that the parts can be arranged in a compact form for transportation, the burner being also detachably connected with the burner-pipe.

Having described our invention, what we claim,and desire to secure by Letters Patent, 1S-

An illuminating apparatus comprising a reservoir for the illuminating agent, a supplypipe connected with the reservoir, a burnerpipe connected with the su )ply-pipe and adapted to revolve in a vertical plane on a horizontal axis, and a burner connected with the bu rner-pi pe, said parts being arranged to form a portable illuminating apparatus, as and for the purposes described.

2. An illuminating apparatus comprising a reservoirfor the illuminating agent, asupplypipe connected with the reservoir, a support for said sup 'ily-pipe, a burner-pipe connected with the supply-pipe and adapted to revolve in a vertical plane on a horizontal axis, and a burner connected with the burner-pipe, said parts being arranged to form a portable illuminating apparatus, as and for the purposes described.
